Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F3743CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 374 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance Parameters (Required):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Variations in dimensional tolerances (length, width, height) within the 1206 package specification do not affect functional substitution. Product status differences are noted for design lifecycle considerations.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Designs: RC1206FR-07374KL (YAGEO) and CRCW1206374KFKEA (Vishay Dale) are both qualified as direct substitutes with Active product status. Both manufacturers maintain full production and support for these components. YAGEO RC1206FR-07374KL offers standard industrial-grade specifications. CRCW1206374KFKEA includes automotive AEC-Q200 qualification, suitable for applications requiring enhanced reliability standards.

For Automotive Applications: CRCW1206374KFKEA (Vishay Dale) carries AEC-Q200 automotive qualification and is the appropriate selection for automotive circuit designs requiring component-level reliability certification.

For Legacy Design Support: ERJ-8ENF3743V (Panasonic) is classified as Not For New Designs. This component remains available in inventory but should not be selected for new product development. Existing designs currently using this part number may continue procurement, but migration to Active status alternatives is recommended for long-term supply chain stability.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the environmental regulatory requirements of the original RC3216F3743CS.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07374KL replace RC3216F3743CS in existing designs?

A: Yes. Both components share identical electrical specifications (374 kOhms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and 1206 package footprint. Both maintain Active product status and ROHS3 compliance. Substitution is functionally equivalent.

Q: What is the difference between CRCW1206374KFKEA and the other substitutes?

A: CRCW1206374KFKEA includes automotive AEC-Q200 qualification, indicating enhanced reliability testing and qualification for automotive applications. All other electrical and mechanical parameters are identical to other substitutes. This qualification is required only for automotive circuit designs.

Q: Why is ERJ-8ENF3743V marked as Not For New Designs?

A: Product status "Not For New Designs" indicates that Panasonic has discontinued active development and marketing of this component line. While inventory remains available and the part is functionally equivalent, new product designs should select from Active status alternatives (RC1206FR-07374KL or CRCW1206374KFKEA) to ensure long-term supply chain availability and manufacturer support.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within 1206 package tolerance specifications. RC3216F3743CS and CRCW1206374KFKEA both measure 0.126" L x 0.063" W (3.20mm x 1.60mm). RC1206FR-07374KL measures 0.122" L x 0.063" W (3.10mm x 1.60mm). ERJ-8ENF3743V measures 0.126" L x 0.063" W (3.20mm x 1.60mm). Height variations range from 0.024" to 0.028" (0.60mm to 0.70mm). All dimensions fall within standard 1206 footprint specifications and do not affect PCB layout compatibility.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly. This matches the original RC3216F3743CS specification.

Q: Which substitute offers the best long-term availability?

A: CRCW1206374KFKEA (Vishay Dale) and RC1206FR-07374KL (YAGEO) both maintain Active product status with substantial inventory levels (23,902 and 6,305 units respectively). Both manufacturers are established suppliers with stable product lines. For new designs, either part provides equivalent long-term supply security.
